I think that if wago are stating maintainance free, and you decided to use that, I wouldn't be advising anything other than a carpet covering over that area of floor and definatly a large marking of white paint with a notice on the board. I was given some of the ashley type once by a home owner who had sourced them after throwing his bulider off site for taping up connector blocks in the wall to extend a ring final circuit. I popped the ashley items in the bin and installed 47mm deep boxed in the wall below coving hight and wired from there, crimped the cables in the 47mm boxes and fitted blank plates. Not very attractive, but nicer to look at than a ripped apart kitchen with holes in the walls which have been made trying to find these ashley boxes.
Just out of interest, why did you chuck the Ashley boxes?
Have you used them before and found them to fail or do you just think they will fail due to their design?
